Formula to populate null rows with specific output

[Khristian_Evans]

I want to populate the null rows in a column with a specific value / output - 12/31/9999. Could someone help with how I could do this please?

@Khristian_Evans can you elaborate on your requirement?

I currently have null rows in my output column that I want to change to 12/31/9999

Hi, this solution didn't work for me 

[binuacs]

@Khristian_Evans @Are you getting any error message or warnings in the result window? Also can you screen shot your formula tool with the data?

@Khristian_Evans, @binuacs's solution should work as long as the requirements you shared are correct! Make sure your data type is a string as "12/31/9999" will have to be stored as such
